[[pl:Just another Perl hacker]]

A [[Perl]] program which prints "Just another Perl hacker," (the comma being [[canonical]] but occasionally omitted)

using extremely [[obfuscated code|obfuscated]] methods, typically ones

Line 8 ⟶ 6:

The obfuscation can result from the code being total gibberish, e.g.:

<pre> $_="krJhruaesrltre c a cnp,ohet";$_.=$1,print$2while s/(..)(.)//;</pre>

or from having "Just another Perl hacker," embedded in opaque code:

<pre> $_='987;s/^(d+)/$1-1/e;$1?eval:print"Just another Perl hacker,"';eval</pre>;

or from looking like it does something simple and completely

unrelated to printing "Just another Perl hacker":

<pre> $_ = "wftedskaebjgdpjgidbsmnjgc";

tr/a-z/oh, turtleneck Phrase Jar!/; print;</pre>

This phrase was popularized by [[Randal L. Schwartz]], who created most of the first such programs in the signatures of his postings to the [[Usenet newsgroup]] comp.lang.perl (the predecessor to the modern comp.lang.perl.misc).
